New study finds SARS-CoV-2 can infect testes

Researchers at the University of Texas Medical Branch have observed that SARS-CoV-2, the virus that causes COVID-19, can infect the testes of infected hamsters. The findings, published in the journal Microorganisms, could help explain symptoms some men with COVID-19 have reported and have important implications for men’s health. As the pandemic goes on, clinicians continue to report their findings that […]

SARS-CoV-2 is detectable—though likely not transmissible—on hospital surfaces

Watching what was happening around the world in early 2020, University of California San Diego School of Medicine researchers knew their region would likely soon be hit with a wave of patients with COVID-19, the infection caused by the coronavirus SARS-CoV-2. They wondered how the virus persists on surfaces, particularly in hospitals, and they knew they had only a small […]

Distinct spike protein mutations in SARS-CoV-2 variant in Russia

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for the coronavirus 2019 (COVID-19) pandemic, has lasted for approximately a year and a half, with over 173 million infections reported worldwide. In spite of having acquired and identified a large number of genetic sequences and variants since the start of the pandemic, scientists still face the challenge of […]

SARS-CoV-2 variants have higher transmissibility and a longer infectious period

Researchers analyzed data on three variants of concern and found that viral loads were higher and infection lasted longer for the B.1.1.7 variant. They all were more infectious than the original strain, and transmissibility also depended on population demographics. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has evolved since it first emerged in late 2019. Several mutations of the […]

Curcumin nanosystems could be powerful COVID-19 therapeutics

With new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerging, the coronavirus disease 2019 (COVID-19) pandemic is far from over. While the global vaccine rollout has moved at an impressive speed, the search for new safe, effective, and targeted therapies is still on. Now, a new study in Biomedicine and Pharmacotherapy reviews the potential for curcumin, a natural […]

Long-COVID-19 is a significant risk in recovered patients post-hospitalization

The ongoing coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pathogen, has claimed the lives of over 2.79 million people worldwide. However, the long-term effects of the virus on human health and lifespan are less well known. A new study, which appeared in the British Medical Journal, reports on a retrospective study to […]

Rare genetic variant may explain severe COVID-19 in young healthy male patients

The novel coronavirus disease 2019 (COVID-19) pandemic has now been spreading for over a year, but several mysteries surrounding its diverse outcomes remain. How is it that some young healthy individuals contract the infection(caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and become critically unwell? Why do others, who are older and have underlying comorbidities, have less severe […]

SARS-CoV-2 positivity in asymptomatic-screened dental patients

Asymptomatic carriage of SARS-CoV-2 is a potentially significant source of transmission, yet remains relatively poorly understood. The study “SARS-CoV-2 Positivity in Asymptomatic-screened Dental Patients” published in the Journal of Dental Research (JDR), investigated SARS-CoV-2 infection in asymptomatic dental patients to inform community surveillance and improve understanding of risks in the dental setting. Thirty-one dental care centers across Scotland invited asymptomatic […]

Nanoparticles elicit neutralizing antibodies to diverse SARS-CoV-2 variants

Spike-protein-based nanoparticle vaccine candidates were retained longer in follicular dendritic cells and showed higher germinal center reactions in lymph node follicles compared to soluble spike protein vaccine. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has infected hundreds of millions worldwide since its emergence more than a year ago. The virus has also been mutating throughout the pandemic, with several […]

Antibody agents effective at neutralizing European, South African, and United States SARS-CoV-2 variants

Researchers in the United States have demonstrated the effectiveness of three antibody agents at neutralizing recently emerged variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent responsible for the coronavirus disease 2019 (COVID-19) pandemic. The team showed that one full-length antibody and two antibody domains each effectively neutralized pseudotyped virus containing key mutations found within the B.1.1.7 […]
